Depends on the surrounding infrastructure of the IFS system. The ring and pinion are small and 37's put a lot of stress on them. Biggest failure point on Dana 30 solid axles comes from case deflection causing gear misalignment causing teeth to break. That and the smaller diameter pinion shaft not being up to the task.Soooooo 37s or no?
The new generation Dana axles have bigger pinion diameter than the old generation and that helps. And the IFS system takes a lot of the stress off the differential housing that a solid axle would see so case deflection would potentially be reduced.
Naturally, a lot of the "will it hold up" discussion is based on how you drive it. Lockers and big rock crawling with a lot of throttle all reduce the chances of it lasting. But careful driving and not a lot of abuse will probably give you a lot longer life.
Best bet is to see what the Ranger crowd is doing and what kind of failures they're seeing.
Personally, I'd upgrade to the 220 because bigger is stronger. But if you aren't going to abuse your Bronco, the 190 may be enough for you.
